Answer 2

Permutation and Combination

The number are $4,2,0,7, 3$ from which 5 digit number are to be made.

For using these digit for making 5 digit number , 0 can't be at the first place.

So, for filling 1st place only 4 options will be there, for all other places 5 options will be there. Nothing specific is given in question, so assuming that repetition is not allowed.

Number of ways for filling first place$=4$

Number of ways for filling second place$=4$

Number of ways for filling third place$=3$

Number of ways for filling fourth place $=2$

Number of ways for filling fifth place $=1$

Hence total number of 5 digit number will be $=4\times4\times 3\times\ 2\times\ 1$=96 .
